This study aims to evaluate two methods of surface water routing including kinematic wave and time-area in upstream of the Bustan dam. To this end, first considering the features and application prerequisites of both methods and describing the hydraulic and hydrologic conditions within the Tamer watershed, algorithms and scripts of kinematic wave and time-area methods were developed. Then the s...

In order to predict storage life of navel orange, The model for the variable regularity of total soluble sugar, total acidity, vitamin C, soluble solids, the sugar-acidity ratio in navel orange according to storage time was established based on BP artificial neural network . The results show that the multi-factor BP artificial neural network model has better predicted effect than single-factor ...

the potential of vis-ir (400–1100 nm) transmittance method to assess the internal quality (freshness) of intact chicken egg during storage at a temperature of 307 oc and 25% 4 relative humidity was investigated. one hundred chicken egg samples were used for measuring its freshness and spectral collection during egg storage times (up to 30 days). two correlation models between haugh unit (hu) an...

The effect of storage time on some properties of groundnut shell briquette with 5, 10, 15 and 20% binder (cassava gel) was studied. The briquettes were prepared using a motorized briquetting machine. The moisture content, durability rating, water penetration, calorific value and the ash content were determined after every 30 days for 6 months. The results reveals that the moisture content of br...
